Jul 10, 2014· Hematite and quartz present in banded iron ore are intimately associated with one another and require fine grinding for the liberation of mineral particles. The influence of the thickness of bands on the liberation and flotation response of banded hematite quartzite (BHQ) ore is investigated.

banded ores, which has not been investigated so far. The characterization study of BIF prior to beneficiation is very important to select a proper mesh of grind and benefi-ciation technique. Characterization studies of banded ores like BHQ and BHJ indicate that these ores are liberated at extre-mely finer sizes (Singh et al. 2015).

Dec 16, 2010· The liberation of hematite particles can be enhanced to about 82% by reducing the particle size to below 63 μm. The rejection of silica particles can be obtained by magnetic and flotation separation techniques. Overall, the BHQ ore can be enriched to 65.3wt% Fe at 61.9% iron recovery.

Hematite(week magnetic ore) is refractory minerals Before, the flotation and roasting-magnetic separating process are mainly used For the past few years, due to the application of strong magnetic separator, undersize sieve etc new equipment and gravity separation equipment, reverse flotation process, hematite (week magnetic ore),
